The width of a rectangular poster is half its length. The area of the poster is 128 square feet. What is the width of the poster?
Let the width be x/2 and the length be x:
(x/2)*x = 128
Multiply both sides by 2 and remove the brackets:
x2 = 256
Square root both sides:
x = 16
Therefore: length = 16 feet and width = 8 feet
Check: 16*8 = 128 square feet
